"Howard (Simon Helberg) and Bernadette have a hard time leaving Halley in day care when Bernadette returns to work. Also, Bert introduces the gang to his new girlfriend, Rebecca (April Bowlby)," the episode listing on The Futon Critic reads.

Meanwhile, Bert has a new girlfriend that he will be introducing to the gang in the season 10 finale of "The Big Bang Theory."

Bert had a big crush on Amy (Mayim Bialik) before, and Sheldon (Jim Parsons) enjoyed being his subject of envy. Now that Bert has a girlfriend, the show has yet to reveal if Sheldon will be happy about it.

With almost everyone being in a relationship, Raj (Kunal Nayyar) is looking for a girlfriend, and he needs his friends to set him up with someone.

As seen from the episode 21 promo, Leonard (Johnny Galecki) asks Penny (Kaley Cuoco) if she has a friend that they can set up with Raj. Penny responded with, "I already set up Howard and Bernadette. It's your turn to ruin some poor girl's life."

Raj even asks Sheldon what attracted him to Amy. Surprisingly, Sheldon says it's her mind and her body. However, Amy explains that Sheldon likes her because they have the same blood type and because he can harvest her organs for himself.

The season 10 finale of "The Big Bang Theory" will air on Thursday, April 13, at 8 p.m. EDT on CBS.
